The Lowdown
Righto, Rusty here. Let’s have a look at what’s cookin’ at Jaconé for the next couple of weeks.
We’ve got a bit of a slow start, but there’s some serious potential building later on, so don’t write the week off just yet.
The water temp is about average for this time of year, nothing out of the ordinary.
First up, Wednesday the 19th and Thursday the 20th are pretty flat and ordinary. Tiny 2ft to 3ft east swell, short 7-second period, and weak energy (63 to 163). Clean enough with light offshore winds in the mornings, but honestly, it’s barely surfable. Not worth paddling out for.
Friday the 21st morning is where things start to wake up. A clean 6ft east-northeast swell with an 8-second period rolls in, moderate energy (529), and a light offshore breeze. That’s your first decent window—expect some fun, clean waves. Friday afternoon goes to crap though as a strong onshore SW wind kicks up and the swell switches off.
Saturday the 22nd is a write-off. Onshore SW winds all day, messy and poor surf. Don’t bother.
Sunday the 23rd morning brings a glimmer—5ft south-southwest swell, glassy conditions with light S winds, and moderate energy (310). That’s a nice little session if you’re keen for a clean, smaller wave. The afternoon gets a bit chopped.
Now, here’s the standout: Monday the 24th through Wednesday the 26th. Monday morning sees a 6ft south swell with a long 13-second period and clean conditions—very good surf (energy 976). By Monday afternoon, it jumps to a 7ft south groundswell, 12-second period, and strong energy (1339). Clean, light winds. This is excellent, but at 7ft it’s getting into experienced surfer territory. Tuesday the 25th morning pumps with an 8ft south swell, 14-second period, and very strong energy (2633)—that’s a proper swell, only for the experienced crew. Offshore ENE winds keep it clean. Tuesday afternoon drops a bit with stronger winds. Wednesday the 26th still has a solid 5ft south swell, 12-second period, and good energy (1051)—another excellent morning for skilled surfers.
After that, the swell backs off. Thursday the 27th morning has a 6ft east-northeast swell, shorter period, but still clean—good for a session. The rest of the week drops into small, ordinary surf through to the end of August and into September.
From the 29th of August onward, it’s pretty poor. Weak swells, onshore or cross-shore winds, and low energy. There’s a small window on the 2nd of September morning with a clean 3ft south swell, but it’s ordinary. The rest is flat or messy.
Bottom line: the best surf by far is from Monday the 24th to Wednesday the 26th of August—solid south groundswell, long period, clean conditions. Get on it if you’re experienced. The Friday the 21st morning is a solid runner-up for a smaller, clean session.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
